In reply to higherclimbingwales:
yeah what he says, i'd prolly use clove hitches on all the gear, give myself a little slack
on the single line to me, then overhand to equalise the 2 bits of gear (using the 'dead' end
from the 2nd bit of gear in the knot as well). Clip into the double loop, add belay device to that (needs to be below you - so not much good for an upward pull !)
